Description

Electric conductivity and Hall coefficient of high quality CdS thin films has been measured, in the temperature range between 177 K and 370 K, using Van der Pauw method. We have found that there are present at least two types of localized centers in this material, one of which find itself both in ground and first excited state. The nature and the energy of these localized centers and the probably dominating scattering mechanisms of free carriers in different ranges of temperature have been established. (authors)
